Resumen

TORRES-INGA, Carlos S et al. Evaluation of Fattening Efficiency of Grazing Bulls through Panel Data Envelopment Analysis. Rev. prod. anim. [online]. 2018, vol.30, n.1, pp.22-29. ISSN 2224-7920.

The purpose of this paper was to assess efficiency changes in grazing bulls through the method of data envelopment analysis, using panel data in two periods of time. The panel data were compiled by DEAP 2.1, with the inclusion of the results of a 3-year period, from 38 private farms (beef production units), at the cooperatives of credits and services, in province of Camaguey, Cuba. The output variable was total sold kg (TSKG); the input variable were cost of Northgold (CN), fuel kg per ha (FKGXHA), fuel kg per livestock unit (FKGXLU), and human labor force (HLF), which were highly correlated to the output variable. Technical efficiency (TE), pure efficiency (PEC), and scale efficiency (SEC), decreased by the third year of fattening, in 0.2, 0.4, and 0.5 %, respectively. Technology change (TC) between the second and third years rose to almost 14 %, and the total productivity factor (TPF) spiked as farmers became more skilled and experienced, with a 4.9 % increase in comparison to the first year, and 13.7 % in the second year.

Palabras clave : overall technical efficiency; scale; productivity factor.
